I have recently started doing the “Scientific 7 Minute Workout”. There has apparently been research showing that short, high-intensity exercise can provide similar benefits to longer duration exercises of less intensity.

I generally do them at home right before my daily shower to stay clean

Sleep naked, get multiples of the same outfits, aim for a “do it now” mentality, get a buzz-cut every few months, give your friends access to your google calendar so hanging out is easier to plan, learn Python to automate repetitive tasks*, and replace carpet with wood or tile.

*Especially valuable if you’re in school. Python saved my butt in high school statistics and number theory.

Biphasic sleep (or diphasic, bimodal or bifurcated sleep) is the practice of sleeping during two periods over 24 hours, while polyphasic sleep refers to sleeping multiple times – usually more than two. Each of these is in contrast to monophasic sleep, which is one period of sleep over 24 hours. Segmented sleep and divided sleep may refer to polyphasic or biphasic sleep, but may also refer to interrupted sleep, where the sleep has one or several shorter periods of wakefulness.

I am a naturally polyphasic sleeper, it seems. My sleep patterns are not based on ideology or some snazzy theory about how I can gain time by sleeping more often, though less in total. I have simply always had a varied sleep pattern, but I have never seen that as a problem. And I always want the total to add up to around eight hours a day, because studies often indicate that important things happen during sleep, and I don’t want to impair my waking awareness.

Regarding muli-phasic sleep, i think it should only be done if it suits your body and mind. For some a monophasic phase sleep…7-8 hrs at a stretch works well while for some multi-phasic (bi or polyphasic) suits well.
